Abstract

Propagation prediction algorithms which use terrain information are typically used for the design of modern wireless systems. Therefore, it is essential that when analyzing the performances of ad hoc networks we observe the network in a natural 3D terrain and we use an appropriate propagation model. In this paper we explain our extension of the NS-2 simulator using Digital Elevation Model data and terrain aware propagation model. Because of the natural emergence of clustering in the network of users, we also study the relationship between the clustering in the ad hoc networks and different terrain profiles. The simulations show that, when the network clusters are accompanied with related terrain contours, the observed network performances demonstrate measurable enhancement.
